The unified skcipher API -seems to have made its entry with 4.3.[3, 4] By what can be seen from -migration patches[1.ff.], it's a drop-in replacement. - -Also, deallocators such as crypto_free_skcipher() are NULL-safe now[2]. - -Add a new header cipherapi.h to aid migration from ablkcipher to skcipher and -retain support for old kernels. Make it decide which API to use and provide -appropriate function calls and type definitions. Since the ablkcipher and -skcipher APIs are so similar, those are mainly defines for corresponding -pseudo-functions in namespace cryptodev_ derived directly from their API -counterparts. - -Compiles and works (i.e. checks pass) with Debian testing 4.6.4 kernel -as well as 4.8-rc2+ Linus git tree as of today.
